Klipsch Synergy Sub-12

When it comes to subwoofers, size still matters. While smaller 6- or 8-inch subs can produce credible bass, once you experience what a well-designed 12-inch model can deliver, you won't want to settle for less. Most big subs come with hefty price tags,...

The Klipsch Synergy Sub-12 is a full-size subwoofer that offers a down-firing 12-inch woofer, a 300-watt amplifier, and connectivity options that cover all bases.

A real wood veneer would look nicer.

The Klipsch Synergy Sub-12, the company's most affordable 12-inch subwoofer, sounds great on music and movies.

Episode ES-SUB-12-300-MB Powered Subwoofer Reviewed

Episode has released their largest subwoofer to date with the ES-SUB-12. While its looks may not be so impressive, HomeTheaterReview.com reviewer Andrew Robinson's evaluation claims the performance is quite the opposite.

The ES-SUB-12's build quality is phenomenal, possessing smooth lines, solid construction and the warranty to back it up. While the finish may not be automotive grade, it's not supposed to be, for the ES-SUB-12 is designed with the intention of being...

The ES-SUB-12's grille is a bit finicky and cheap, but then again, you'd probably leave it off when installing it into an AV cabinet anyway ; I'm sure many will criticize the ES-SUB-12 for its simplicity, for many subs in its price bracket feature some...

To say that I was impressed following my time spent with Episode's big daddy subwoofer, the ES-SUB-12, is a bit of an understatement. At first glance, there's little to get excited about, for the ES-SUB-12 appears to be behind the times in terms of...

"Awsome...best bang 4 ur buck!!"

I have had this sub for over 3 years. Never a flaw or problem. Unlike my JBL. It broke twice and did not sound as clear at higher volumes. This sub is as good at low settings as well as high settings. Clear all the way thru the spectrum. Highly...

Beats any sub I have heard, or purchased. Much better than 10" sub.

I cannot find any.

"For this price this sub is perfect!!"

This is the second subwoofer I've owned and so far the best. My previous sub was a 10" JBL that was rated very good but it had a relatively short life and stopped working after only a year old. That JBL was a good sounding sub but it wouldn't be able...

A good 12" sub that sounds tight but doesn't get boomy. Features extra line outs for hooking up to main speakers. This sub does what you want it and makes enough bass to vibrate your body should you feel the need.

Its pretty ugly, It's kinda huge, it's blue led light on it is blinding. I had to put a piece of tape over the led to tone down the brightness a little.

Product Specifications

The Synergy Series Sub-12 hurls out enough power and bass extension to shake the foundation. It uses high-quality materials and the most reliable components to create a rock-solid impact that makes your movies and music come alive.The Sub-12 gets its intensity from a 12-inch, down-firing driver coupled to a highly efficient BASH Class D amplifier that creates 300 watts of continuous power and 650 watts of dynamic power. Because of its ample enclosure size and large, rear-firing port with flared ends, the Sub-12 produces increased bass response with low distortion.The subwoofer's built-in, steep-slope (24dB/octave) low-pass crossover is continuously adjustable from 40 to 120Hz. A phase control facilitates acoustical integration of the subwoofer with the other speakers in the system. An "auto power" feature enables the subwoofer to turn itself on and off (standby) automatically, based on the presence or absence of an audio signal. A blue/red dual color LED display on the front of the subwoofer indicates whether the unit is on or in standby mode.In addition to its ability to play louder and go deeper than anything else in its class, the Sub-12 features a new industrial design that is refined and aggressive. Available in a black finish with titanium accents, this extraordinary subwoofer matches the entire Synergy Series lineup in both style and performance.Because it wraps technical superiority and eye-catching cosmetics into one affordable package, the Sub-12 perfectly anchors a home theater or two-channel system.
